My car currently has Boxster calipers front and rear and I am running Boxster wheels. I like the look of 15" Fuchs so I am looking at the Maxilite 15x6 wheels. Anyone out there running Boxster calipers with 15" wheels? Just wondering if they fit. I don't know anyone that has a 15" wheel to test. Thanks.

What rotors are you running? That's a key factor...I'm guessing Carrera (impact bumper) rotor?
I'd be surprised if 15" fit, the 16" I use look like they don't have a lot of room to spare. Anyone else have a set of 15" fuchs and tried it? |

You might have to make a template and share it so someone can measure a wheel if not local...

I am running Stoptech Carrera rotors in front and 911sc in back. It looks like there is plenty of space but could be wrong Attached thumbnail(s)

I run 7x15" (fake) Fuchs with Boxster calipers with no issues. You can think about potential clearance issues in 2 ways / axes: 1) the radial clearance (i.e. radially to the inner curved surface of the wheel well) and 2) the offset clearance (to the rear face and contours of the wheel center).
Given early (non S) Boxster calipers were designed to fit under 15" wheels, and the fact that most mounting adapters are aiming to place them so they can use 86-88 Carrera rotors (as Nathan points out), radial clearance (issue 1) is not usually a problem. No doubt there are some 15" rims somewhere in the world that prove this wrong, but with my rims there looks to be a 10mm radial clearance between caliper and wheel. The offset clearance is where you have to focus. Different rims and offsets, in combination with hub depth chosen (think there are a few variants from Porsche?) can absolutely give clearance issues. I run a lot of wheel spacer to fill out the GT fenders (obviously helping caliper clearance), but on a narrow body car this is restricted. Anyway, so to the OP's question: I am over on the Peninsula - PM me if you want to meet sometime and test fit on your car. I have a 6x15" (real) Fuch as a spare we can try. - Tony |

That makes sense. |

They fit real fuchs but not all fakes are the same dimension.

Here is the description of the Maxilite from their website: 6x15, off set ET 36, 5x130, optics as original deep six, matt black centre with diamond cut lip, fits Porsche 911 and 912 up to MY 1976 all around, also front axle of Porsche 911 to MY 1980, not SC 204 HP, Carrera 3,2 or turbo. No caps included |

No caps included Wondering why they say that, besides being too narrow for aesthetics? Or do they have larger brakes? Remember that due to be castings they could be a tad thicker which would be for the most part all on the inside area for the brakes. |
